hello, I'm trying to apply multidimensional scaling to my data set. orngMDS seems to work fine for this task, except for one thing...

I would like to be able to change the dimensionality of the output from the default (2D), but I can't seem to manage it. I understood that the "dim" variable was the dimensionality of the projected space, and yes, I seem to be able to set this to any value I want, but the output is always a set of 2D vectors. Am I understanding this wrong? or is there something else that I could try? Any ideas would be great!

One thing I did notice when setting a value for dim is that the variable is not recognised when first initialising the MDS class (though it's implied in the documentation that I can do this), but it can be set separately:

I just fixed this. The dim argument was treated as a positional and not as a keyword argument.You can update orange from svn and the your code should work, or just replace your:mds = orngMDS.MDS(dists, dim=3)with:mds = orngMDS.MDS(dists, 3)
